Various treks involve routes from Salkantay Mountain: one joins the Inca Trail at Huayllabamba, then proceeds as before on the main Trail through Wiñay Wayna to Machu Picchu. To get to Salkantay, you have to start in Mollepata, north west of Cusco on the Apurimac valley, Salkantay to Machu Picchu take five nights or three nights or seven nights. A seven-nights trek goes from Paucarcancha, a camping site on the trek from Salkantay, to Huayllabamba, then on the traditional Inca Trail to Machu Picchu. Paucarcancha is a abandoned set of ruins on the descent from Pampacahuana, before the village of Huayllabamba on the main Inca Trail. There are some hot springs nearby.

Salcantay (Nevado Salcantay) or Salkantay (Nevado Salkantay) is the highest peak of the Willkapampa mountain range, part of the Peruvian Andes. It is located in the Cusco Region, about 60 km (40 mi) west-northwest of the city of Cusco. It is the 38th highest peak in the Andes, and the twelfth highest in Peru. However, as a range highpoint in deeply incised terrain, it is the second most topographically prominent peak in the country.
And while the Salkantay may not possess the international brag factor of the Inca Trail, its advantages are many. The Salkantay Trek offers a different experience to the Inca Trail and delivers the best landscapes of the Salkantay mountain as well as superb hiking.
The Salkantay Trek is also a more strenuous alternative to Inca Trail, the altitude is higher in several places and there is some steep, rugged terrain to tackle. With that said, a little bit of prior fitness training goes a long way and people of all ages, in good physical condition, with some hiking experience will do fine on this trek.
